Flexural response of concurrently 3D printed sandwich composite [PDF]

open access: yes, 2020
Among many lightweight materials used in marine applications, sandwich structures with syntactic foam core are promising because of lower water uptake in foam core amid face-sheets damage. HDPE (high-density polyethylene) filament is used to 3D print sandwich skin, and glass microballoon (GMB) reinforced HDPE syntactic foam filaments are used for the ...

Bending of chiral fractal lattice metamaterials [PDF]

open access: yesarXiv, 2022
We describe the out-of-plane bending of chiral fractal lattices metamaterials by using a combination of theoretical models, full-scale finite elements and experimental tests representing the flexural behaviour of metamaterial beams under three-point bending. Good agreement is observed between the three sets of results. Parametric analyses show a linear

Flexure updates to MOSFIRE on the Keck I telescope [PDF]

open access: yes, 2020
We present a recent evaluation and updates applied to the Multi-Object Spectrometer For Infra-Red Exploration (MOSFIRE) on the Keck I telescope. Over the course of significantly long integrations, when MOSFIRE sits on one mask for $>$4 hours, a slight drift in mask stars has been measured. While this does not affect all science-cases done with MOSFIRE,

Properties of nanocellulose and zirconia alumina on polymethylmethacrylate dental composite

open access: yesDental Journal, 2023
Background: Polymethylmethacrylate (PMMA) is one of the synthetic polymers generally used for temporary jacket crown restorations because of its good translucency, making its aesthetic value higher, but its mechanical properties, such as hardness and ...
